Claims (10)
1. ~An aqueous mixture comprising:
(a) from 15% to 65% of at least one borohydride compound;
(b) from 1% to 10% of at least one metal hydroxide; and (c) from 0.1% to 20% of at least one absorbent polymer or excipient.
(a) from 15% to 65% of at least one borohydride compound;
(b) from 1% to 10% of at least one metal hydroxide; and (c) from 0.1% to 20% of at least one absorbent polymer or excipient.
2. ~The aqueous mixture of claim 1 in which said at least one borohydride compound is sodium borohydride, potassium borohydride or a combination thereof; and said at least one metal hydroxide is sodium, lithium or potassium hydroxide, or a combination thereof.
3. ~The aqueous mixture of claim 2 in which said at least one absorbent polymer or excipient is selected from among water-soluble polymers, cellulose and its derivatives and cross-linked polymers.
4. ~The aqueous mixture of claim 3 in which the borohydride compound is sodium borohydride and the base is sodium hydroxide.
5. ~The aqueous mixture of claim 4 having from 2% to 8% sodium hydroxide and from 20% to 50% sodium borohydride.
6. ~The aqueous mixture of claim 5 in which said at least one absorbent polymer or excipient is polyacrylic acid or a copolymer of acrylic acid having at least 50% acrylic acid monomer units.
7. ~The aqueous mixture of claim 6 having from 0.1% to 1% polyacrylic acid or acrylic acid copolymer, and in which weight average molecular weight of the polyacrylic acid or copolymer of acrylic acid is at least 1500.
8. ~A method for stabilizing an aqueous borohydride mixture containing from 15% to 65% of at least one borohydride compound and from 1%
to 10% of at least one metal hydroxide; said method comprising adding from 0.1% to 20% of at least one absorbent polymer or excipient
to 10% of at least one metal hydroxide; said method comprising adding from 0.1% to 20% of at least one absorbent polymer or excipient
9. ~The method of claim 8 said at least one metal hydroxide is sodium hydroxide and said at least one borohydride compound is sodium borohydride.
10. ~The method of claim 9 in which the aqueous borohydride mixture has from 2% to 8% sodium hydroxide and from 20% to 50% sodium borohydride.
